Arthropod Lighting System Spectral Control

The patent extracts and removes the harmful UV-A (360-400 nm) and blue (400-480 nm) wavelength components from the lighting spectrum while retaining the beneficial green (480-580 nm) and red (620-700 nm) components. This is achieved by using specific LED combinations that emit only in the safe wavelength ranges, effectively taking out the harmful portions of the spectrum that cause disease and mortality in arthropods.

The patent changes the spectral parameters of the lighting system by defining specific wavelength ranges with minimum and maximum spectral power values. The lighting system is configured to provide green light (480-580 nm) with spectral power EGM and red light (620-700 nm) with spectral power ER, while maintaining E2/E1≤0.005 for UV-A and E3/E1≤0.025 for blue light, where E1 is the total spectral power in the visible range. This parameter control ensures arthropod health while promoting growth.

The patent segments the lighting spectrum into distinct wavelength ranges (UV-A: 360-400 nm, blue: 400-480 nm, green: 480-580 nm, red: 620-700 nm) and controls each segment independently using specific LED types. This segmentation allows precise control over the spectral power distribution in each range, enabling the system to promote arthropod growth while avoiding harmful wavelengths. The segmented approach simplifies the control complexity by treating each wavelength range as a separate controllable unit.

The patent uses a multi-functional lighting system that simultaneously achieves multiple objectives: promoting arthropod growth through green and red light, preventing disease by excluding UV-A and blue light, and providing a standardized spectral power distribution that can be applied to various arthropod species. The system combines LED technology with defined spectral parameters to create a universal solution for arthropod farming that addresses multiple health and productivity requirements in a single integrated approach.
